The invention provides a VM migration method for P-E trade-off of seasonal non-steady concurrency, and relates to the technical field of cloud computing. The method comprises two parts of VM static deployment and VM dynamic migration. Firstly, static deployment of VMs is carried out according to memories and CPU resources provided by a physical server and needed by the VMs, the VMs are deployed tophysical hosts under the condition that the process meets the requirements of customers, meanwhile, the number of the physical hosts is reduced as much as possible, and the purpose of reducing energyconsumption is achieved. And after the VM is statically deployed, VM migration is finished by adopting a VM dynamic migration strategy. The method comprises two parts, in the first part, the averageresponse time of each VM is predicted by using an RBF algorithm, and the VM needing to be migrated is selected according to a set threshold value; in the second part, a target server is selected, thetarget server is selected through the updated resource demand matrix, and VM migration in one stage is completed; the first part and the second part are circularly carried out to finish the whole VM migration process.
Description
technical field [0001] The invention relates to the technical field of cloud computing, in particular to a VM migration method for P-E trade-off of seasonal non-stationary concurrency. Background technique [0002] The virtualization technology can effectively utilize existing software and hardware resources, and a virtual machine (Virtual Machine, VM) can also be created by using the virtualization software. The VM acts as an independent entity on the network, which facilitates the sharing of hardware-related resources. Under the right circumstances, migrating a VM from one physical host to another can significantly improve the overall performance, energy consumption, and flexibility of cloud service-related systems. Virtualization technology can help cloud service providers achieve orderly on-demand resource deployment, and provide effective solutions for flexible resource management and energy consumption reduction. For cloud services with virtualization, one of its mai...
